Malleable Fitting：
Malleable fittings are commonly used for electrical conduit and various plumbing connections. The malleable fitting gets its name from the type of iron from which it is cast — white iron. Upon casting, it is a very brittle metal. Through the process of annealing, the white iron is softened into one of the three forms of malleable iron.
The plumbing industry used malleable fittings and pipes for many years until copper, PVC, and PEX pipe became more economical. Due to concerns about chemicals such as zinc leaching into drinking water, galvanized malleable fittings are no longer commonly found in home plumbing systems. While the malleable fitting is still in use for high pressure applications.
